Title: The Detection of Gravitational Waves with LIGO

Abstract: Gravitational wave emission is expected to arise from a variety ofastrophysical phenomena. A new generation of detectors withsensitivity consistent with expectation from such sources is beingdeveloped. The Laser Interferometer Gravitational-Wave Observatory(LIGO), one of these ambitious undertakings, is being developed by aCaltech-MIT collaboration. It consists of two widely separated interferometers, which will be used in coincidence to search forsources from compact binary systems, spinning neutron stars,supernovae and other astrophysical or cosmological phenomena that emit gravitational waves. The construction of LIGO is well underway and preparations are being made for the commissioning phase. In thislecture, I review the underlying physics of gravitational waves,review possible astrophysical and cosmological sources and discuss theLIGO interferometer status and plans.
